The pressure in the water supply pipes is 4 * 10/5 Pa to what height the water from the fire pipe connected

The pressure in the water supply pipes is 4 * 10/5 Pa to what height the water from the fire pipe connected to this water supply will beat, if we do not take into account the air resistance and friction of the pipe.

To solve this problem, it is necessary to find the height of the liquid column that creates the pressure P. For this, we use the formula known from physics. Where p = 1000 (kg / m3) is the density of the liquid. Where h is the height of the water column. Where g = 9.8 (m / s2) is the acceleration at the earth’s surface. Where P = 4 * 10 ^ 5 (Pa) – water pressure.

P = p * g * h. From here we find the height of the water rise.

h = P / (p * g) = (4 * 10 ^ 5 (Pa) / (1000 (kg / m3) * 9.8 (m / s2)) = 40.81 (m).

Answer: the height of the rise of water will be h = 40.81 (m).
